Opticom OPERA OPR-003-CTR-X Quick start guide

Brand: Opticom

Model: OPERA OPR-003-CTR-X

Type: Quick start guide

The OPERA™Voice/Audio Quality

Analyzer represents the latest

developments to objectively eva-

luate and assure the quality of

compressed voice and wide-band

audio signals, based on modeling

the human ear. With OPERA you

can achieve a comprehensive ana-

lysis of the end-to-end quality of

today's and next generation net-

works, such as 3G VoIP, VoDSL,

VoATM, ISDN, GSM, POTS, from

the caller to the callee. Also, you

can test the audio quality of com-

pression formats such as MP3,

AAC, AC3, Microsoft Windows

Media, from the studio source to

the receiver, or from the server to

the client.

For the test engineer, one of the

issues is how to apply a computer

model of the human ear to a test

circuit, or to a live network envi-

ronment. For this reason, OPTICOM

developed OPERA as an open, easy

to configure hardware platform

that can process perceptual

models, which are implemented

just by software. The basis of the

OPERA system is a portable 'lunch

box' type of PC host system. Four

slots can take various kinds of

interfaces. Alternatively, OPERA is

now also available in a rack-moun-

table form factor. For R&D and lab

applications, a cost effective soft-

ware-only version with reduced

functionality is offered, as well.

Supported Operating Systems

are Microsoft Windows NT™,

Windows™2000, Windows™XP,

Windows™2003.
